What a Section 8 notice is, and how much notice it has to give

Since 1 May 2026 there is one route for a landlord in England to end a tenancy against the tenant's wishes, and this is it. A Section 8 notice states the statutory ground or grounds you are relying on, and gives the notice period that the law attaches to those grounds.

Two things follow from that sentence, and they are the two things most worth understanding before you serve anything. The reason has to be one the law recognises. And the length of notice is not yours to choose.

The notice period comes from the ground

Under Section 21 the reason did not matter and the period was fixed. Under Section 8 the reason is the case, and the period follows from it. Pick a ground, and you have picked how long the process takes.

The ranges are wide. A landlord who needs the property back for their own family gives four months. A landlord dealing with three months of arrears gives four weeks. Two of the grounds carry no statutory minimum at all.

That has a practical consequence people discover late: if you are relying on more than one ground, the longest notice period among them applies. Selecting an additional ground as a belt-and-braces measure can quietly extend your notice by months, so it is worth being deliberate rather than thorough.

Mandatory and discretionary, which matters more than the notice period

Every ground is one or the other, and the difference is the most consequential thing on this page.

• Mandatory. If you prove the ground, the court must order possession. It has no discretion to weigh up the circumstances.
• Discretionary. Proving the ground is not enough. The court must also be satisfied that it is reasonable to order possession, taking the whole situation into account.

A discretionary ground is not a weak ground, but it is a different kind of case: you are asking a court to agree with you rather than to apply a rule. Ground 8 (serious arrears) is mandatory. Ground 10 (some arrears) is discretionary, for the same underlying problem at a smaller scale.

The sixteen grounds, grouped by the notice they require

These are the grounds relevant to an ordinary private residential landlord. Grounds that apply only to registered social landlords, universities, agricultural employers and mortgage lenders are left out, because they will not apply to you.

Four months

• Ground 1 — you or a close family member need to move in. Mandatory.
• Ground 1A — you intend to sell the property. Mandatory.
• Ground 6 — the property needs redevelopment or demolition. Mandatory.

Two months

• Ground 7 — an inherited tenancy, where the holder was not living there before the previous tenant died. Mandatory.
• Ground 9 — suitable alternative accommodation has been offered. Discretionary.

Four weeks

• Ground 8 — at least three months' rent arrears, or thirteen weeks where rent is paid weekly or fortnightly. Mandatory.
• Ground 10 — some arrears, below the Ground 8 threshold. Discretionary.
• Ground 11 — the tenant has persistently delayed paying rent. Discretionary.

Two weeks

• Ground 7B — the tenant has no right to rent under immigration law. Mandatory.
• Ground 12 — breach of a tenancy term other than rent. Discretionary.
• Ground 13 — the tenant let the property's condition deteriorate. Discretionary.
• Ground 14ZA — the tenant or an occupant has been convicted of a rioting offence. Discretionary.
• Ground 15 — the tenant let furniture provided with the property deteriorate. Discretionary.
• Ground 17 — the tenant gave false information to obtain the tenancy. Discretionary.

No statutory minimum

• Ground 7A — the tenant, or someone living with or visiting them, has been convicted of relevant criminal behaviour or breached an anti-social behaviour injunction. Mandatory.
• Ground 14 — nuisance or antisocial behaviour by the tenant or a visitor. Discretionary.

No minimum notice does not mean immediate possession. A court order still cannot be issued within 14 days of the notice. That is a constraint on the court process rather than on the notice period, but the effect on your timeline is the same.

A notice is not possession

Serving a Section 8 notice starts a process. It does not end a tenancy, it does not oblige anyone to leave, and it gives you no right to take the property back yourself.

If the tenant does not leave by the date on the notice, the next step is a possession claim in the county court, and the tenancy continues — with rent continuing to fall due — until the court says otherwise. Anything that looks like taking possession without a court order is a different and much more serious matter.

Choosing the right ground, evidencing it, and serving the notice correctly is a legal decision with real consequences if you get it wrong. This post describes the shape of the system. It is not advice about your situation, and a possession case is one of the clearest examples of when to take some.

How Tenarize handles it

When you record a notice, you select the grounds you are relying on from the sixteen above, each shown with its type and its statutory minimum. Tenarize calculates the earliest valid expiry date from the grounds you selected — taking the longest period where you have picked several — and pre-fills it, editable if you need to give longer.

A Notice card records that a notice was served independently of actually ending the tenancy, because those are two different events that can be months apart. It drives a reminder if the tenant has not left by the expiry date, which is the point at which a landlord usually needs to decide what to do next.

What it does not do is tell you which ground applies. It records what you have done and keeps the dates straight.

For advice on a specific case, Shelter and Citizens Advice are free and independent, and a possession claim is worth taking proper advice on.

A possession case is built on evidence, and evidence is only available later if somebody recorded it at the time — which is usually months before anyone imagined needing it. Tenarize records the grounds and the notice with its expiry date, and keeps an audit trail per tenancy you can export.

It is £15 a month for one to five properties, with the first month free. The help centre is free to read either way.
